A member asked:

Patella pop when bending my knee after acl reconstruction. worried?

Maybe: If this was a patellar tendon autograft might be related. Otherwise can be scar tissue, graft impingement, cyclops lesion or damage to the graft or meniscus. Can also be related to the screws or fixation method for the graft. Gets complicated. See your dr.

Generally not.: The "pop" may be related to you breaking up some scar tissue, or it could be altered tracking of the kneecap, which should improve with physical therapy.
